which will satisfy clothes washing, dish

can scald and permanently injure you
upon contact. Some people are more
likely to be permanently injured by hot

or state law requiring a certain
temperature water at the hot water tap,
then you must take special precautions.
In addition to using the lowest possible
temperature setting that satisfies your
hot water needs, some type of
tempering device, such as a mixing
valve, should be used at the hot water
taps used by these people or at the hot
water heater. Mixing valves are
available at plumbing supply or
hardware stores. Follow
manufacturer’s instructions for
installation of the valves. Before
